New Clausing 6913 - Gear box engagement lever fixed!!!!

IMG_20170430_195001901.jpg Hello again. I've spent the last 2 afternoons cleaning this thing up. Lot of work!!! Does anyone know what tool post this is? I have one broken attachment and it seems solid. Might try to replace the broken one.
 
IMG_20170430_194947568.jpg Does anyone have experience with this gear box engagement assembly? I have had it in and out of the machine at least 30 times trying to make it work. It was loose when I got it(the bolts holding it to the gearbox were about to fall out and the box was out of oil, the cover fell off on to the trailer when I pulled out of his yard to. I got it to work, but it doesn't seem correct. The way it feels now is like the coil spring inside it is useless. I'm sure its in there for a reason. I just want it correct and I don't believe it is right now, although it works good. One part according to the parts diagram was in wrong. One other part inside the cover had signs of pliers on it to so I'm assuming he was having trouble with it as well. Thanks again!

I don't know your machine gear box
But you are doing right . Keep looking at drawings
Parts brake downs . Asking questions until you are satisfied that it is working right just the way it should . Never give up or settle for oh well that's good enough
 
I won't give up. Too stubborn I'm going to call clausing tomorrow and see what they say so I have my fingers crossed at the moment. Hopefully some food news from them.

Going by memory so bear with me. You pull on the knurled part of that handle to disengage the handle so you can turn/change the numbered dial in front. If you try and push down on that knurled handle assembly it will want to spring back up, more so at the bottom of its travel. This part is iffy memory. Just behind that handle is a safety ratchet mechanism so that in the event of a crash when feeding/threading, it spins. The lathe also has safety/soft pins in the right places. And the handle should be at more like 5 Oclock in the locked position. You have it at 12.
 
That sounds correct. When you push the handle down, it raises a set of gears in the gearbox to engage the feed screw. The handle that pulls, disengages a pin that matches up to a notch in the housing it rotates on. allowing the internal gearset to rotate down and disengage the feed screw. It does have a ratcheting mechanism as well inside it(one way clutch type of set up) The handle will lock in the 5 oclock position, where its at now it is just disengaged at the time of the pic. The spring inside the mechanism doesn't seem to do anything(there is no tension on the handle from spring pressure) It SEEMS to me it needs to be assembled and maybe pre-tensioned while installing to make it all work correctly but I haven't been able to find the sequence or order. Its got me baffled.
 
gear box engagment lever assy.jpg Her is the mechanism giving me trouble. It appears everything Is there. It just doesn't function correctly. Will post a pic of the gears it rotates to engage the feed screw shortly.

It can be zoomed in enough to read from across the room!!!! Its a very large picture in the manual. The manual is at 15% of the original size so you can zoom in a long ways.

Untitled.jpg Circled in red it the gearset that is rotated upwards to engage the feed screw. The items circled in green do the rotating, although this shows only one gear at the right hand end of the gearset engagement lever. My machine has a 2 gears that mesh with both sets of teeth on the rotating gearset(Gear cradle)

I understand that it can be challenging sometimes when somebody before you has “touched it”. It’s much easier to fix it when it’s factory original. It’s a good thing you have the parts breakdown docs. And you also have The Hobby Machinist for help. When you have a bit of time, start at it. And take pictures as you go. Be careful of that clock spring. It has a lot of stored energy as it sits. Don’t go and try to take it out. Just look at it. Check its ends and the rest of the spring. Be looking for a break(s) in the coil and or torn ends. Then check the rest of the parts in that assembly for problems or maybe missing stuff. Reference your parts doc as you go and don’t forget the pics and be safe….Good Luck, Dave.
